Preheat fan-forced oven to 180°c and line a baking tray with baking paper.

To make the dressing: in a small bowl, mix together the oil, tahini and miso paste. In a large bowl, add all the vegetables and dressing and toss thoroughly to ensure well combined. Season to your liking.

Transfer the vegetables onto the baking tray and bake for 25-30 minutes, until tender. Serve with a drizzle of walnut oil.
